Explanation

Sessile flowers lack a pedicel (stalk) and are attached directly to the receptacle. In head inflorescences (capitulum) like those of Asteraceae, the florets are sessile and densely packed on the enlarged receptacle. Tridax, Helianthus (sunflower), Musa, and Vernonia all have head inflorescences with sessile florets.
